Imagine yourself on the highest mountain in the world. You have to deal with the physiological effects of extreme altitude--along with bone-chilling temperatures, battering winds, and a climbing team that's counting on all of its members to make smart decisions. There's simply no room for poor judgment -- one mistake or misstep can result in an "unrecoverable error." In any situation where lives on are the line or the stakes are exceptionally high--there's no better training ground for leaders than settings where people are pushed beyond their perceived limits. Drawing on her experience as team captain of the first American Women's Everest Expedition, Alison Levine makes a compelling case that the leadership principles that apply in the world of extreme adventure also apply to today's rigorously competitive business environments.
